Walk Behind as a "Trail Mower"????

I saw a guy mowing with a JD 600 (or 700 series) tractor with a 5' belly mower pulling two walk behinds on either side. Someone had told me about this before, but I thought they were wrong and he was just pulling a regular trail mower.
This may be good idea, I thought of a way to set up a hitch on mine to try. I'm gonna mount a reciever on the front anyway, so I can mount attachments. I'll just make a hitch attachment for it, I can then use the tongue from the trail mower I have now until I make another.
I hope this set up may be comparable with the Dixie Chopper Pup, but you can still use the walk behind alone if wanted.
If I go thru with it, I'll post pictures. If I see that cat with the 2 walks behind, I'll get a picture of it also.

A WB mower runs at least $2k. You can get 2 48" trail mowers for the same money. If you have a more serious need for this type of mower just get a PTO driven mower for the JD. It seems to me like a lot less hassle.

Do not meddle in the affairs of dragons. Because you are crunchy and taste like chicken.

If it was too much trouble, I wouldn't have done it.
It took about 2 hours to make the tongue, about another 2 hours to rig the weights and get it adjusted right. The walk behind can convert in the field in less than a minute to run by itself.
I've been running this set up for over a month now - it saves me time in my particular case. I'd never buy a walk behind just to tow behind. This is a 345, it doesn't have a PTO.

alta- you de man! obviously you use the walk full time and running both on an open acres makes sense. I would think the walk would cut at a faster speed by itself, as it probably has a higher tip speed than the JD. On large open lots, makes sense to me. One man maximizing equipment and production.
